How to have multiline inputs in Editable Table

    How can I accept new lines in Editable Table with a textarea (input with >= 2 lines)?

    When I press "Enter", the row is automatically saved.


    Editable Table does not support inputs with new lines. However, you can use Javascript to work around the limitation.

    1. Make sure the textarea input has the Name property set (e.g. myTextArea).

    2. Right after this input, add an expression with property Escape Content set to No.

    3. Change the expression's Example property to something more meaningful, such as "<Script: Allow Enter>".

    4. In the Expression value, enter the following Javascript, replacing myTextArea with the name of your input:

    <script language='javascript'>  
    $('#" + myTextArea.Id + "').keyup(function <br>(e) { 
        if <br>(e.keyCode == 13) {
            var <br>ta = this;  
            var <br>caretPos = ta.selectionStart;   
            var <br>textAreaTxt = $('#';   
            var <br>txtToAdd = '\n';  
            ta.selectionStart = caretPos + txtToAdd.length;   
            $('#', caretPos) + txtToAdd + textAreaTxt.substring(caretPos));
            ta.selectionStart = caretPos + txtToAdd.length;   
            ta.selectionEnd = caretPos + txtToAdd.length;   

    The script monitors the keys that the user presses in the input. If the script detects an "Enter", it inserts a newline, and stops the propagation of the event. Therefore, the Editable Table won't see the key press.

    In the end, you should have something similar to the example below:
